It handles better.

Tucked into the IPL G Coupe's wheel wells are large 19-inch aluminum alloy
wheels shod in grippy 225-width tires up front and 245-width tires out back.
Twenty-percent stiffer springs suspend the vehicle over these upsized rollers.
Stiffer springs usually beget a stiffer ride, but thanks to tweaks that have
been made to the IPL G Coupe's dampers, the sports coupe doesn't feel
dramatically more bone-jarring over low-speed bumps and cracks than a standard
G37 with the Sport package. You may recall that we Car Tech editors were of
split minds as to whether the standard Sport package's ride is too harsh to
begin with, but at least in this case the rougher ride matches the IPL's racy
character.

While the IPL doesn't feel much different from the standard G37 while
moseying around town. I discovered on a windy road that its handling limits feel
noticeably higher than more mundane Gs. Moreover, those limits are approached,
met, and -- if you're not careful -- exceeded in a much more predictable and
controlled manner than the standard G Coupe as well.

Usually when a performance car features upgraded bodywork, it means that the
automaker has slapped on a new front bumper, rear diffuser, side skirts, and
sometimes a spoiler to make the car in question look more aggressive. This is
exactly what Infiniti did with the IPL G Coupe -- spoiler and all. However, in
this case the new body work actually serves an aerodynamic purpose, creating a
zero-lift condition by helping to control how air moves around the vehicle at
high speeds.
